Thank you WoolRoom... This Alpaca king, (all season) duvet is amazing. my wife suffers from night sweats, and having read your details concerning the advantages of this duvet for this problem we bought it. My wife found using the TWO quilts together, (even at this time of year) was too much, but the thicker of the two alone has proved to be wonderful. It is very light, but keeps her warm without heavy weight, we are very pleased indeed. Also, I must say that I am sleeping better than I have for years. I feel really warm and so comfortable, waking up really refreshed, I would also say that I am over eighty and find the need for deep comfortable sleep very important.... so its thank you WoolRoom from me as well as my wife.
